MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains multiple embedded URLs and a document body that explicitly mentions 'More Robux' and 'hack', indicating a lure for game-related exploits. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests it is designed to redirect users to download malicious content. The primary IOC is the external URI http://netcdn.tw/app/431946152/more-robux-game-hack, which likely hosts the second-stage payload.
